What is Lightning ransomware? And how does it implement its attack?

Lightning ransomware is a new variant of Everbe ransomware and like other Everbe variants, it is designed to lock important data in an infected computer and demand a ransom from its victims. Specifically, Lightning ransomware is the variant of Everbe 2.0 ransomware and uses the .lightning extension in marking the files it encrypts.

Lightning Ransomware

Once its malicious payload reaches the targeted computer, Lightning ransomware, it connects the computer to a remote Command and Control or C&C server managed by the attackers. After that, it downloads more malicious components that are used for its information gathering and stealth protection modules. It first starts to employ the data gathering module used to gather data about the infected system and the personal information of the user(s).

The harvested information, along with some malicious components is then used for the stealth protection module used to keep the crypto-malware invisible in the system from any programs that might interfere with its attack. Moreover, it might also make changes in the Windows Registry so that it can automatically every time you start your computer. After that, it looks for files with the following extensions:

.doc, .docx, .jpg, .lnk, .pdf, .xls, xlsx

It targets the very same file types as Everbe 2.0 ransomware. And just like Everbe 2.0 ransomware, Lightning ransomware also uses either the AES or DES cipher in locking the targeted files. Following data encryption, it drops a file named “!=How_to_decrypt_files=!.txt” which contains the following message:

“Hello! All your files have been encrypted!
Don’t worry, we can help you to return all of your files.
If you want to know the price for the decryptor, write to our email – [email protected]
In the subject write – id-8f821b2589c3.
Every 7 days price doubles.
If within 24 hours we didn’t answer you, write to our backup mail – [email protected]

How is the payload file of Lightning ransomware distributed over the web?

Just like Everbe 2.0 ransomware, Lightning ransomware spreads using several tactics such as unprotected RDP configuration, deceptive downloads, botnets, exploit kits, fake software or software updates, and spam emails. Although it mostly uses spam emails with malicious attachments used to install the crypt-malware in the system.
